In Dawko's video where he shows the teaser photos, there's this one set in where Mollie Macaw was decapitated, there is a blood trail, but Mollie's head and body were both gone, so someone must've taken it.

My initial suspect was Salem, because they did corrupt Mollie in the minigame, and she has the potions. Maybe the potions will revive Mollie, but in a corrupt form, allowing her to return in future installments. That minigame might be foreshadowing what will happen in the future.

However...

Then there was this picture. I am going to assume it's the same bloodtrail, and it went into Lloyd's theatre. So it must be Lloyd who took the body because he is hungry. He might have done this in the past too, because of the blood on his body.
